BOTTLE- STOPPER- SPECIFICATION forming part of Letters PatentNo.'340,20l, dated April 20, 1886.

Application filed October 12, 1885. Serial No. 179,678. (No model.)

To all whom t may concern:

Be it known that I, BENJAMIN K. Doa- WART, a citizen of the UnitedStates, residing at Lancaster, in the county of Lancaster and State ofPennsylvania, have invented certain Improvements in Bottle-Stoppers, ofwhich the following is a specification.

My invention relates to a device for dropping or pouring liquids fromthe mouths of bottles or vessels of a similar character; and the objectsof my improvements are, rst, to provide a stopper through which liquidscan be discharged from or emptied into a vessel without removing saidstopper; and, second, to discharge such liquids either by drops or by acontinuous stream.

My device is particularly valuable as a means for dropping or pouringmedicine from a bottle without removing the stopper, for by it the dropscan `be delivered of a uniform size and at a uniform rate, while asimple turn of the bottle enables the contents to be poured out in acontinuous stream.

I attain the objects mentioned by the mechanism illustrated in theaccompanying drawings, in which- Figure 1 is a side elevation of abottle with my device attached; Fig. 2, a vertical section through thebody of the stopper; Fig. 3, an elevation of the spigot; Fig. 5, anenlarged vertical section of the lower part of the device, and Figs. 4and 6 show side views of a different arrangement of the tubes. Fig. 7shows the stopper turned in position to be used as a dropper.

Similarletters refer to similar parts throughout the several views.

A represents the body of my stopper, which consists of a faucet open atboth ends, and of such diameter as to enter the mouth of the vessel withwhich it is used, having a flange, a, encircling it and projecting overthe sides of the mouth of the vessel, and two openings, B, in its sideslocated opposite, or nearly so, to each other, which are adapted toreceive tubes b b' of any required size or shape.

luto the top of the faucet A a spigot, D, is

inserted, constructed to t closely on the same, having openings dthrough it to correspond with those in the faucet.

The spigot has a milled head, h, and extends to the bottom of thefaucet, where a portion, e, of its lower edge is turned outward, so asto lap the part f of the lower edge of the said faucet.

A segment, g, ofthe lower edge of the faucet is cut away, so` as to forma recess, in which a teat, t, which projects from the lower edge of thespigot, engages.

In operating my device the spigot, which is of course closedvat the topand open at the bottom, has its movement in the faucet regulated` by theteat t and the length of the recess g, theteat resting against the endof therecess, where the openings d of the spigot coineide with those Bin the faucet, and against ,the other when the spigot is turned, so asto completely close the openings B.

The tubeb has. an orifice just sufficiently large to allow enough fluidto pass through and form drops on the outer end, while the tube b has anopening great enough to permit a constant flow. In addition to this`difference in the capacity of the tubes they are of use for anotherpurpose. The openings in the faucet and spigot being arranged so thatthose on both sides coincide at the same time, one tube serves to supplyair-while the other is discharging the duid.

The operation of my device will be readily understood from the precedingdescription.

The position of the two parts of the stopper are such that the openingsB d coincide Vwhen it is desirable to use either tube, and when theoutlets are to be closed the spigot is turned by means of its milledhead h.

Figs. 4 and 6 show modified forms of my device, the former of whichshows a stopper, which can be used for coal-oil or similar cans, and thelatter as Stoppers for bottles, which it may be wished to fill, or fromwhich the liquid can be transferred without removing the stopper.

' The gasket used can be of any desirable material, and the relativeshape and size of the tubes b b extending therefrom, and the hollow rovarious parts of my device can be changed, as faucet, which fits insideof the stopper, and is may be deemed best. provided with openings d tocorrespond with Having thus fully described my said inventhe tubes, andthe stop upn its lovver end, tion, what I claim as new, and desire tosecure substantially as shown and described. by Letters Patent, is BENJ.K. DORWART.
